Just original white Apple band that came with the watch.Are you wearing a watch band with magnets?
All location switches are on.
I just won't use compass. I give up.
I have tried using the warranty on my AW4 before and they need to have the watch for a week.You do, um, have a Series 5, right?
If so, it's under warranty, get in touch with AppleCare and have them figure it out or fix/replace your Watch.
If not, well, ahem.
